Created attachment 490000 [details] testcase ###!!! ASSERTION: We should have padding here! (out of memory?): 'hasPadding', file layout/generic/nsFrame.cpp, line 693
I don't know why bug 550325 was a blocker, but this might need to be a blocker for the same reason.

I don't know either.

I guess bug 550325 was a blocker because it's pure HTML+CSS and there was an actual layout error involved, so it could potentially have broken some site. This bug (which is the padding variant of bug 586628) involves XUL boxes in HTML and it's just a harmless assertion - no layout regression. I think we should just mute these assertions for XUL boxes until we actually implement percentage padding/margin for them.

Noting here that attachment 508920 [details] [diff] [review] should be backed out when this bug is fixed.
Only happens for XUL frames.

Still affects Windows at least (other platforms don't seem to reproduce easily on Try anyway).
